I bought the wrong end caps for the SE slipons that I bought. The end caps are #65066-01, Billet double groove. They cost me $50.72 each from Zanotti's. Zanottis will charge me 20% to return them I think. If anyone would like them I will sell them for $35 each plus shipping. PM me if you are interested. One box has been opened and one box is still sealed.

I bought the 64985-07A slipons and they are 4" in diameter. The end caps that I have are 3.25" in diameter.
